It’s easier the higher the overall cost of housing. Training more people in trades can be lower labour costs. Doesn’t have to follow usual government principle of ultra comfy job to give out as political favours. Affordability due to small size makes it easier to break even while affordable. Just because you target a break even price, doesn’t mean you won’t sell to highest bidder.

More supply is what lowers cost of housing, and targetting break even gives a pricing advantage over profit/scarcity model. So do decisions prioritizing affordability over luxury.
